5 Wellness Trends That Are Completely Overhyped

The wellness industry is worth over $5 trillion globally. It sells hope, aesthetics and the language of science — often without the science itself. As someone who studied molecular biology, I find the gap between what is claimed and what is evidenced both remarkable and genuinely frustrating.

This is not an anti-wellness post. Evidence-based lifestyle changes genuinely improve health. But distinguishing between what has evidence and what has effective marketing protects both your wallet and your health. Here are five of the most widely sold wellness ideas that do not hold up to scientific scrutiny.

1. Detox Teas and Cleanses

The concept of "detoxing" through teas, juices, or protocols implies that your body accumulates toxins that require external removal. This is biologically implausible. Your body runs a continuous, highly sophisticated detoxification system involving the liver (phase I and II biotransformation), the kidneys (filtration and excretion), the lungs, lymph system and skin. These systems operate 24 hours a day regardless of whether you drink a special tea.

When companies market "detox" products, they are never able to specify which toxins are being removed, via which biological mechanism, or provide clinical evidence of measurably reduced toxin load after use. Because no such evidence exists. The active laxative ingredients in many detox teas (often senna) produce the rapid weight change users interpret as detoxification — what is actually happening is water loss and bowel evacuation.

If your liver or kidneys are genuinely failing to detoxify your body, you require medical treatment — not a herbal tea. If they are functioning normally, you do not need to supplement their function.

2. Alkaline Water

Alkaline water (pH 8–9.5) is marketed on the premise that drinking it shifts your body's pH to a more "alkaline" state, thereby preventing disease, improving energy and optimising cellular function. This is a fundamental misunderstanding of human physiology.

Your blood pH is maintained within an extraordinarily tight range of 7.35–7.45 by a system of chemical buffers (bicarbonate-carbonic acid system), respiratory regulation (CO₂ exhalation) and renal excretion. Any significant deviation from this range — acidosis below 7.35 or alkalosis above 7.45 — is a medical emergency. Your body will not allow alkaline water to meaningfully shift blood pH, regardless of how much you drink. The stomach immediately acidifies anything you consume to pH 1.5–3.5 for digestion.

No peer-reviewed clinical trial demonstrates health benefits of alkaline water in healthy individuals beyond normal hydration. The one area with some emerging evidence is acid reflux — where the high pH may temporarily buffer oesophageal acid — but this is a very specific and limited finding.

3. Activated Charcoal in Food and Drinks

Activated charcoal lattes and supplements became aesthetically popular partly because of their dramatic black colour. The wellness claim: activated charcoal binds toxins in the gut and removes them. The reality: activated charcoal does bind substances in the gut — but indiscriminately.

In genuine emergency medicine, activated charcoal is used for certain poisoning cases within one hour of ingestion. It works — but in that specific, clinical context. As a daily supplement, it binds not just hypothetical "toxins" but also medications (including contraceptive pills and antibiotics, reducing their effectiveness) and dietary nutrients. Regular use of activated charcoal around meal times can impair nutrient absorption and interfere with prescribed medicines. The clinical consensus is that there is no benefit to healthy individuals and a real risk of harm through drug interaction.

4. Collagen Supplements — The Nuanced One

This is the most nuanced entry on this list because collagen supplements are not entirely without evidence — but the evidence is often misrepresented. The claim that oral collagen supplements directly improve skin collagen is mechanistically oversimplified. Dietary collagen (like all proteins) is broken down into amino acids during digestion and does not travel intact to skin cells to "top up" your collagen stores.

However — and this is where it gets interesting — there is evidence that the specific peptides produced by collagen hydrolysis (particularly Pro-Hyp and Gly-Pro-Hyp) may act as signalling molecules that stimulate fibroblast activity. Several randomised controlled trials have shown statistically significant improvements in skin hydration, elasticity and collagen density with hydrolysed collagen supplementation at doses of 2.5–10g daily over 8–12 weeks.

The evidence is real but modest, and many collagen products are significantly overpriced for what they contain (essentially hydrolysed protein). You can support your body's own collagen synthesis more cost-effectively by ensuring adequate vitamin C (essential for collagen hydroxylation), zinc, glycine-rich protein sources and — most importantly — daily SPF to prevent UV-driven collagen degradation. See our beginner skincare routine for SPF guidance.

5. IV Vitamin Drips for "Wellness"

Intravenous vitamin infusions — Myers cocktails, glutathione drips, vitamin C IVs — have moved from clinical settings into wellness clinics and even hotel spas. The premise: bypassing digestion delivers vitamins more effectively, boosting energy, immunity and even skin brightness.

The clinical reality: IV administration is necessary when someone cannot absorb nutrients orally (severe gastrointestinal conditions, certain malabsorption disorders, critical illness). In a person with a functioning digestive system, oral absorption of most vitamins is highly efficient and bioavailability is not meaningfully limiting. High-dose IV vitamin C has some evidence in specific oncology contexts — but this is a very different claim to general wellness.

Beyond the lack of efficacy evidence for healthy individuals, IV drips carry non-trivial risks: infection at the cannula site, air embolism, vein damage, anaphylactic reactions, and — with high-dose vitamin infusions — electrolyte imbalances. Performing these procedures outside regulated medical environments, by insufficiently trained practitioners, has caused documented patient harm. The risk-benefit profile for a healthy person seeking an "energy boost" simply does not support the practice. According to guidance from the World Health Organization, unnecessary injections and infusions carry risks that are unjustified when safer alternatives exist.

What Actually Has Evidence

The evidence-based foundations of good health are remarkably consistent across the research literature: sleep 7–9 hours at consistent times, eat a varied diet rich in plants and fibre, move your body regularly, manage chronic stress, maintain social connection, avoid smoking and limit alcohol. None of these require expensive products. They require consistency — which is harder to sell than a supplement.
